Structured products provide the holder of that product with an economic, legal or other interest in another asset (the "underlying asset") and hence derive their value by reference to the price or value of the underlying asset. Characteristics of these products include, but are not limited to:

(1) The underlying asset may be a security, index, currency, commodity or other asset or combination of such assets. Where the underlying asset is two or more securities, indices, currencies or other assets the products are generally referred to as "baskets";
(2) The products may allow investors to purchase the underlying asset at a predetermined price or at a price calculated by reference to a predetermined formula; to sell the underlying asset at a predetermined price or at a price calculated by reference to a predetermined formula; to receive a cash payment (or payments) calculated by reference to the price or value of the underlying asset; or provide holders with other forms of interest in the price or value of the underlying asset;
(3) For the purposes of determining the cash payments to holders of the product the underlying assets may be valued one or more times prior to the final expiry or maturity date, each such time a valuation is performed being referred to in these rules as an interim Valuation Point. Any cash payment calculated at an interim Valuation Point may be distributed to holders after the valuation has been performed or it may be carried forward and aggregated with the cash payments calculated at other Valuation Points (including the Final Valuation Point) before being paid to holders after the final maturity date;
(4) The products may be American style (where exercise is permitted prior to the expiry day), European style (where exercise is only permitted on the maturity date of the product), or other style as approved by the Exchange from time to time;
(5) The products may be collateralised or uncollateralised. Where products are collateralised the issuer owns all of the underlying securities or other assets to which the collateralised product relates and grants a charge over such securities or assets in favour of an independent trustee which acts for the benefit of the holders of that product. Where products are not collateralised the obligations of the issuer are provided for in a form other than by way of a charge over the underlying securities or assets. Non-collateralised products are usually issued by financial institutions which will adopt hedging strategies to provide for their obligations during the life of the non-collateralised product;
(6) The products may require investors to make one or more payments during the life of the product to acquire the underlying securities or assets;
(7) The products may provide for investors to receive an amount equivalent to any dividends (or other distributions) on the underlying asset during the life of the structured product;
(8) The products may or may not be capital protected (i.e. where the issuer guarantees that all or a certain proportion of the initial subscription price for the product will be payable to investors when the product matures);
(9) The return to investors may be subject to an upper limit (often called a cap) or may also contain "knock in" or "knock out" features
